Last week, a bit of controversy erupted over an anti-Semitic cartoon posted by Benjamin Netanyahu’s adult son on Twitter; apparently, he had misread it as mocking George Soros’s person rather than using the financier as a stand-in for an international Jewish conspiracy. Jewish reactions to the incident, as Shmuel Rosner writes, bring into sharp contrast the divergent perceptions of anti-Semitism in Israel and the United States:

Because of Israel’s circumstances and assumptions, Israeli Jews haven’t developed the same sensitivity and ear for anti-Semitism that Jews elsewhere have. . . . The younger Netanyahu hasn’t yet explained himself, but I have no doubt that he’s not an anti-Semite. . . .

Since the only anti-Semitism Israelis understand is one of violence, blood, and brutal intimidation, it is hard for many of them to appreciate [many American Jews’] panic over, [for instance], a few hundred marchers [in Charlottesville] and the ineloquent condemnation of [them by] the president. Since the only remedy for anti-Semitism they know is a Jewish state (and its Jewish army), it is hard for many of them to appreciate fears about anti-Semitism that are not followed by immigration to Israel.

But most of all, what should Israel do? Just consider some of the options. Assist American Jews in some material way? They seem to be doing fine. In fact, they seem to feel confident enough to fight their own fight. Any attempt by Israel to intervene in this crisis would suggest that the Jews of America are not as integrated as they claim to be.

Join the chorus of condemnation? Israel doesn’t need to prove that it dislikes neo-Nazis. But as a country, it has other interests. First and foremost is its need for good relations with the American administration—the same administration that many American Jews blame for the crisis. Moreover, Israel has an aversion to leftist radicals like the ones who clashed with the white supremacists in Charlottesville because many of these radicals are associated with groups highly critical of Israel’s policies, who often support boycott of Israel—a stance that most Israelis believe is as anti-Semitic as the anti-Semitism of the right. . . .

The only thing that Israel can really offer in response to anti-Semitism is something tried and true: its existence.

On Tuesday, a Hizballah drone attack injured three people in northern Israel. The next day, another attack, targeting an IDF base, injured eighteen people, six of them seriously, in Arab al-Amshe, also in the north. This second attack involved the simultaneous use of drones carrying explosives and guided antitank missiles. In both cases, the defensive systems that performed so successfully last weekend failed to stop the drones and missiles. Ron Ben-Yishai has a straightforward explanation as to why: the Lebanon-backed terrorist group is getting better at evading Israel defenses. He explains the three basis systems used to pilot these unmanned aircraft, and their practical effects:

These systems allow drones to act similarly to fighter jets, using “dead zones”—areas not visible to radar or other optical detection—to approach targets. They fly low initially, then ascend just before crashing and detonating on the target. The terrain of southern Lebanon is particularly conducive to such attacks.

But this requires skills that the terror group has honed over months of fighting against Israel. The latest attacks involved a large drone capable of carrying over 50 kg (110 lbs.) of explosives. The terrorists have likely analyzed Israel’s alert and interception systems, recognizing that shooting down their drones requires early detection to allow sufficient time for launching interceptors.

The IDF tries to detect any incoming drones on its radar, as it had done prior to the war. Despite Hizballah’s learning curve, the IDF’s technological edge offers an advantage. However, the military must recognize that any measure it takes is quickly observed and analyzed, and even the most effective defenses can be incomplete. The terrain near the Lebanon-Israel border continues to pose a challenge, necessitating technological solutions and significant financial investment.
